Interface: dropdown for setting weapon's damage type should have current damage type selected

[Badziew]

There are a few skills (e.g. Exalted Archer) that allow characters to switch damage type of a weapon, and there is a dropdown in action list to do that. Unfortunately that dropdown defaults to first damage type on the list, I suggest that it would instead default to currently set weapon type, to avoid player confusion about which damage type is selected - currently the only way to check that is to go to location that has someone or something that can be attacked and see what damage type is displayed in attack dropdown.
